The TOS wardroom was a redress of the briefing room, while the Undiscovered Country wardroom was a re-dress of the USS Enterprise-Dobservation lounge. The DS9 wardroom made its first appearance in the DS9 Season 3 premiere, "The Search, Part I". However, its appearance in "Wrongs Darker Than Death or Night" indicates that the wardroom existed on Terok Nor during the Bajoran Occupation. In the BritishRoyal Navy, the wardroom is the mess cabin of naval commissioned officers above the rank of sub-lieutenant. It is a place where these officers can relax when off-duty though there is a strict etiquette to be followed. The captain of the ship is not usually a member of the wardroom, though can be invited in by its members.
